The simple answer? No. According to the Gallup website:
Your first completion of the Clifton StrengthsFinder will yield the purest and most revealing results. For this reason, each Clifton StrengthsFinder access code is valid for only one use to take the assessment.
Taking the Clifton StrengthsFinder more than once may actually decrease the accuracy of your results. The Clifton StrengthsFinder measures the presence of talents by presenting you with a pair of statements, then challenging you to make a top-of-mind choice between the two. The 20-second time limit and your unfamiliarity with the statements ensure your assessment’s accuracy by making it difficult to over-think your responses.
At CoreClarity, we agree with Gallup on this issue. Once you have taken the assessment, you know too much to take it again in an objective fashion.
Regardless if you remember the specific statements or not, your brain has an understanding of how the assessment works. This can affect your top of mind answer, which is where our talents are triggered. In addition, in cases where someone gets a talent that they don’t want the first time, their subconscious may even skew their subsequent results away from something that could be a very powerful, undeveloped gift.
Some people change jobs after they take the assessment and the new job may require different skill sets and ways of working, so they believe they need to take the assessment again to reflect their new way of being.
In this instance, if you think of it like handedness most people have a dominant hand. It is the one they tend to use easily, naturally and extremely effectively. If you are right-handed, even if you break your right arm, you’re still right-handed. You might just use your left hand more effectively than the right one for a while, but the dominant hand is still the dominant hand!
From a scientific perspective, both Gallup and CoreClarity believe that our talents are based on the synaptic connections in the brain. Although the skills/knowledge/experience that gets added to the core talents will vary over time, the foundational connections still exist. So, a situation might favor using our talents very powerfully or it may not support using our talents at all. But those talents are still there, and they are the elemental building blocks that are the source of our greatest strengths.
